Title: Magnetic head for magneto-optical recording
Inventor: IWATA HITOSHI
IPC: G11B11/105
Filed: 1988-02-24
Abstract: PURPOSE:To improve the efficiency of a core formed into a U-shape by facing the open edge parts of the core with a recording medium and making a magnetic field from either of the opening edge parts act on a vertical magnetizing film. CONSTITUTION:A magnetic head 2 is formed by fixing a core 24, which is composed of Mn-Zn ferrite as a soft magnetic material and formed into the U-shape, to one edge of a slider 21 formed into a plate shape with a nonmagnetic material by a fixing material 25 composed of glass. Further, while a coil 23 is wound around either of the open edge parts of the core 24 at the nearest distance of 0.1-0.8mm from the open edge part, the magnetic head 2 is composed so that the magnetic field from the open edge part can act on the vertical magnetizing film. Consequently, a closed magnetic circuit can be formed on the open edge part at which the core 24 is opposed to the recording medium, leakage flux is made larger, and the magnetic field to act on the recording medium is increased. Thus, the efficiency can be increased.

Title: Reflector of headlamp for vehicle
Inventor: KUME KENJI
IPC: F21S8/10
Filed: 1995-03-01
Abstract: PURPOSE: To eliminate a difficulty in the machining of a mold and prevent the collection of liquid in undercoat and top coat and the reduction of light distribution characteristics by giving a radius of curvature to a reflection face and a stepped face to connect adjacent blocks on a curved face in a section where reflection faces of respective adjacent blocks cause a difference in steps in a boundary section. CONSTITUTION: Adjacent blocks K1, K2, L1, L2' are connected smoothly in such a manner that a reflection face and a stepped face do not form a ridge angle and intersect, for example, by forming a face r (having a radius of curvature) in a boundary section on outer periphery of the block L2'. When the block L2' which is close to a light source position 11 is connected to a difference in steps d' which is latent by means of the r face r, the difference in steps does not form a shadow on the block L1 which is distant from the light source position. As a result, the manufacture of a mold becomes easy and durability is improved. Furthermore, since there is no edge in a raw material of a formed reflector, the collection of liquid in undercoat and top coat in the vapor deposition treatment of aluminum reflection film does not occur, and light distribution characteristics are improved.

Title: Recording and recording medium applied therefor
Inventor: SUZUKI KATSUMI
IPC: B41J2/32
Filed: 1989-02-22
Abstract: PURPOSE:To increase printing speed significantly by heating a specified area on a recording medium using a thermal head, then allowing the heated area to change between an amorphous phase and a crystalline phase and thereby the optical properties of the heated area to record characters. CONSTITUTION:A card consists of a magnetic recording layer 21, a white layer 22 which conceals the former, a dielectric protecting layer 23, a phase change recording layer 24, a dielectric protecting layer 25, and an organic system protecting layer 26 formed sequentially on a substrate 20. The phase change recording layer 24 records printed characters without forming holes due to thermal destruction, then changes from an amorphous phase to a crystalline phase due to the heating of a thermal head. When a material is used which has a different refractive index between the crystalline phase and the amorphous phase and a lower absorption coefficient in the crystalline phase than in the amorphous phase, it is possible to print characters in white due to the white layer 22 as a color for the background of the recording layer 24. In addition, when the material is used which has a contrarily higher absorption coefficient, it is possible to print characters in black. Thus the basically thermal head only has to be heated upto a level higher than a temperature at which the recording layer 24 becomes crystallized and characters can be printed with low energy.
